Pedal operated paddy threshers are widely used in the rice growing countries such as India, Bangladesh, Bhutan,
Korea and some African countries. Thresher-drive linkage plays a vital role in human-machine interaction and workload on
the human operator. The four-bar linkage design used in pedal operated paddy thresher was replaced with four alternative
designs of thresher drive-linkages to assess the load application pattern and physiological work load while operating the pedal
operated paddy thresher. The machine was tested with five operators for physiological workload estimation. The linkage
combinations were found to have significant effects at 1% level on the work pulse rate and workload to operators.
Considering the force-displacement relationships and physiological workload on the operators, linkage three was found to be
the most promising design with lowest work pulse rate of 45.90 beats min-1 and change in energy expenditure rate of 214.5 W
(12.87 kJ min-1).
